    • Lambertellol A (1) is slightly less stable than lambertellol B (2). So, 2 was mainly used for derivatizations. When 1 was subjected to acetylation conditions, polar materials were only observed by the TLC analysis.

    • We succeeded in preparing 13 on a small scale by another route including a disiloxanylidene formation of diol 8 and the following similar reactions to those described in the text. We have not met difficulties in this scheme. However, this needs 14 steps of reactions for preparing 12 and 14 from 8. The scheme in the manuscript requires totally 11 steps for preparing both of them from 8. Taking the total efficiency into account, we adopted the route in the manuscript.

    • 50 values for the triols (17, 18, 19, and 25) and their enantiomers (ent-17, ent-18, ent-19, and ent-25) were estimated to be more than 100 μg/mL in each case.

    • It is hard to discuss the biological activities of the intact 1, 2, and 4 and their enantiomers because of their instabilities in these experiments.
